NOVELTY - Antibacterial fiber comprises 90-180 pts. wt. dimercapto succinic acid, 5-10 pts. wt. protein fiber, 0.04-0.1 pts. wt. graphene oxide, and 0.02-0.08 pts. wt. quaternary ammonium salt and water. USE - Used as antibacterial fiber. ADVANTAGE - The fabric has high bacteriostatic rate and good antibacterial durability effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of the antibacterial fiber comprising: (1) preparing modified fiber: mixing the dimercapto succinic acid with protein fiber, ultrasonicating, water washing to obtain modified protein fiber; preparation of Modified graphene by soaking the graphene oxide with alkali solution, and mixing the graphene oxide after soaking with the quaternary ammonium salt aqueous solution, ultrasonicating, drying to remove water, obtaining modified oxidized graphene; and (2) mixing the modified protein fiber with modified graphene oxide, ultrasonicating, water washing, and drying.
